Hi
This is so important for me.
I installed latest version of (SoftEther VPN client + VPN gate plugin). I use win 10.
when I want to connect with TCP mode immediately error code 2 appears.
"Error (Error Code 2) Protocol error occurred. Error was returned from the destination server."
I can connect in UDP mode But I want to use TCP mode. TCP mode worked just one day. It's interesting that my friend by his PC connect without problem...https://i.stack.imgur.com/1GcpN.jpg
